pahole suggestion: swap position of 'm_rt_count'
before: pahole -C sdw_stream_runtime drivers/soundwire/soundwire-bus.ko
struct sdw_stream_runtime {
const char * name; /* 0 8 */
struct sdw_stream_params params; /* 8 12 */
enum sdw_stream_state state; /* 20 4 */
enum sdw_stream_type type; /* 24 4 */
/* XXX 4 bytes hole, try to pack */
struct list_head master_list; /* 32 16 */
int m_rt_count; /* 48 4 */
/* size: 56, cachelines: 1, members: 6 */
/* sum members: 48, holes: 1, sum holes: 4 */
/* padding: 4 */
/* last cacheline: 56 bytes */
};
after: pahole --reorganize -C sdw_stream_runtime drivers/soundwire/soundwire-bus.ko
struct sdw_stream_runtime {
const char * name; /* 0 8 */
struct sdw_stream_params params; /* 8 12 */
enum sdw_stream_state state; /* 20 4 */
enum sdw_stream_type type; /* 24 4 */
int m_rt_count; /* 28 4 */
struct list_head master_list; /* 32 16 */
/* size: 48, cachelines: 1, members: 6 */
/* last cacheline: 48 bytes */
}; /* saved 8 bytes! */

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
